Helicobacter pylori (H. pylori) is a gram-negative flagellated bacterium that inhabits the gastric environment of 60.3% of the world population, and its prevalence is particularly high in countries with inferior socioeconomic conditions, exceeding 80% in some regions of the globe , This phenomenon occurs among other reasons, due to the unsatisfactory basic sanitation and high people aggregations observed in many under developed nations, scenarios that favour the oral-oral and fecal-oral transmissions of H.pylori.Another possible transmission route of this pathogen is the sexual route. Several studies have shown that the colonization of H.pylori could be negatively and positively associated with the induction and progression of several diseases .It has been reported to be linked to gastric and duodenal ulcer, gastric carcinoma, and gastric mucosa-associated lymphoid tissue (MALT) lymphoma and gastritis ,A positive association also reported between H.pylori infection and oesophageal cancer. Moreover, evidence is also available on the positive association between H.pylori and non gastrointestinal diseases such as diabetes mellitus , coronary artery disease , and anaemia. Abdominal pain and discomfort, nausea, burping, and loss of appetite are common symptoms of H.pylori infection. Other symptoms include, bloating, weight loss, and heart burn. Several approaches are used in the detection of H. pylori. Both the invasive and the non-invasive methods are employed in the detection of H. pylori in a patient. Many factors, however, influence choices in the method of diagnosis: availability of diagnostic instruments/materials, sampling population, and competency and experience of the physicians/clinicians . Invasive methods include endoscopic evaluation, histology, rapid urease test (RUT), and bacterial culture. Non-invasive methods include urea breath test (UBT), stool antigen test (SAT), serology, and molecular diagnostic approaches .Endoscopy is an accurate test for diagnosing the infection as well as the inflammation. Endoscopy also allows the determination of the severity of gastritis with biopsies as well as the presence of ulcers, MALT lymphoma and cancer. Real-time endoscopy along with conventional white light imaging (WLI)and image enhanced endoscopic (IEE)techniques, such as narrow-band imaging (NBI), linked color imaging (LCI) and blue laser imaging (BLI), appear to have important roles in clinical practice to identify H. pyloriinfected status . Another endoscopic technique is i-scan digital chromoendoscopy, which is a digital contrast method that enhances minute mucosal structures and subtle changes in color . The overall diagnostic accuracy of i-scan is 97% compared to 78% for WLI .
Patients referred to internal medicine wards are becoming increasingly complex and fragile. Despite deep knowledge of their specific disorders, steps are required to improve overall management of their acute and chronic conditions. The main objective of the study is to identify demographic, clinical, laboratory and radiological markers of disease severity and activity in patients with diseases treated at general medicine wards (respiratory disease, immune-mediated disease, sepsis, metabolic disease, rare disease, frailty, pregnancy pathology) in order to improve their diagnosis, monitoring and treatment processes.
This is a randomized, double-blind, placebo-controlled Phase Ib/IIa study to evaluate the safety, tolerability, efficacy, pharmacokinetics, and immunogenicity of XW001 inhalation in children with RSV infection in China
The microbiome, the collection of microorganisms that live in our gut, plays an important role in maintaining our health, proper nutrient absorption, nutrient turnover and immunity. After birth, a symbiotic relationship develops with the strains of bacteria that colonise our gut, and the presence and proportion of bacteria is individualised and highly variable. A healthy bacterial flora is essential for the cells of the intestinal mucosa. Glycoproteins in the cell surface mucus coat are important nutrients for bacteria, while some bacterial strains supply mucosal cells with nutrient molecules (e.g. short-chain fatty acids) that are their essential energy source. An abnormal change in the proportion of bacterial strains that make up the microbiome, dysbacteriosis, in which pathogenic bacteria proliferate at the expense of members of the normal flora, can cause a number of pathologies. Nutrient supply to the cells of the mucosa is reduced, making them more vulnerable and leading to various pathological conditions. The microbiome and the essential nutrients they produce have also been found to play an important role in wound healing. A decrease in the diversity of the microbiome, an increase in the relative number of pathogenic bacteria and a decrease in the proportion of 'beneficial' bacteria increases the risk of surgical complications of infection and suture failure.
Infections with SARS-CoV-2 result in a systemic disease with a variety of outcomes, from no symptoms to severe and diverse pathologies. Therefore, it is important to identify risk factors determining COVID-19 severity, especially if those factors might be adjusted, allowing early and effective therapeutic interventions. Zinc is a trace element essential for human health. Zinc deficiency is common in old adults, vegetarians and patients with chronic inflammatory diseases. This condition causes immune dysfunction leading to increased risk of inflammatory and infectious diseases, including acquired immune deficiency syndrome, measles, malaria, tuberculosis, and pneumonia. Besides, zinc has a direct antiviral activity against specific viruses like rhinovirus, HCV, herpes simplex virus. In this scenario, it has been shown that zinc supplementation has benefits on the recurrence and persistence of acute and chronic viral infections like common cold or HCV, HBV. Moreover, our team has recently done an observational study with 249 COVID-19 patients that showed how COVID-19 patients with lower plasma zinc content had worse prognosis, increased time of hospitalization and mortality. Therefore, the main aim of the project is to explore the therapeutic benefit of zinc supplementation for COVID-19 patients and to determine the cellular and molecular basis of the effect of Zn levels on SARS CoV-2 infections. For that purpose the investigators will run a clinical trial supplementing with zinc COVID-19 patients. Moreover, the investigators will carry out experiments to understand the association between zinc nutritional status and SARS-Cov-2 infection progression in cellular and animal models. Given the current knowledge about zinc supplementation toxicity and dosage, the investigators expect that recommendations derived from this study will be rapidly applied by physicians and public health decision makers. The results of these studies will be used as a guideline to administer zinc supplements in COVID-19 patients in order to reduce disease severity and mortality. Moreover, the experiments will clarify whether zinc supplementation as a prophylaxis strategy is useful to protect the population at risk of zinc deficiency, more than 20% worldwide. Finally, considering the new knowledge that this project will generate about the role of zinc in immune responses and viral expansion, the investigators expect that our results will help researchers and physicians to design novel strategies to boost specific immune cell subpopulations against SARS-CoV2 infection. Thus, this knowledge could be used long-term for designing medicines against SARS-CoV-2 and other viral infections.
The primary aim of this study is to detect incidence of mesh infection in cases presented with obstructed or strandulated hernia.A prospective controlled study will be carried out after obtaining written informed consent from all patients and approval of the ethics committee of the faculty of medicine, Assuit University.
H. pylori is transmitted from individual to individual and causes chronic active gastritis in all infected people. H. pylori infection can result in gastroduodenal ulcers, atrophic gastritis (AG), gastric carcinoma, and gastric MALT lymphoma. More than 90% of gastric carcinomas are linked to H. pylori infection that causes chronic AG. A long course of the disease leads to the loss of gastric glands (chronic AG) followed by gastric intestinal metaplasia (GIM), dysplasia, and cancer. This defines two cancer prevention strategies: primary that consists of detection and eradication of H. pylori and secondary that focuses on endoscopic screening for pre-neoplastic lesions and follow-up. Primary prevention planning requires reliable information on the H. pylori prevalence in the population. To design secondary prevention measures, an understanding of the age-sex structure of precancerous changes in the gastric mucosa (the prevalence of atrophic gastritis) is necessary. H. pylori eradication is the basis of primary prevention of gastric cancer (GC). Approximately 36,000 new cases of GC are registered in the Russian Federation each year, and more than 34,000 patients die from the disease. Men get sick 1.3 times more often than women, the peak incidence occurs at the age of over 50 years. The poor outcomes reflect the late stage of diagnosis of this potentially preventable and treatable cancer. The lack of up-to-date data on the H. pylori prevalence in Moscow hinders developing of measures for the detection and timely treatment of this infection as well as the reduction of GC morbidity and mortality.
The goal of this observational study is to evaluate the protective effect of immune barrier on secondary infection after COVID-19 (coronavirus disease 2019) vaccination or COVID-19 virus Omicron B A. 5.2 strain infection by dynamically monitoring the COVID-19 antibody titer, cellular immune function and the occurrence of secondary infection of healthy participants, mainly medical staff in our hospital, to understand the cross protective effect of COVID-19 antibody on different variants of Omicron, and explore the best time to use COVID-19 vaccine to strengthen immunity after Omicron mutant infection.
